jose.j.bonilla 1 Report post Posted November 30, 2019 I've been trying to activate on a new computer but my serial # is coming back as inactive. Is there a way to activate on a new machine? Share this post Link to post Share on other sites
Leslie V. 0 Report post Posted December 2, 2019 Hello Jose, Please uninstall the old version of Nitro Pro and install Nitro Pro 13. You can get the correct version 13 installers from this page: https://www.gonitro.com/nps/product-details/downloads After installation, you can activate by opening Nitro, click on the Help tab > About Nitro Pro > Activate and enter your serial number. Please let me know how that goes. Share this post Link to post Share on other sites
